100% of
relays are tested at 10 - 20 kHz @ 50% duty cycle, @ 8V or greater control
input, at >10mA, and a 10 volt or greater dc load. With a strong control
input signal, this provides:

20kHz PWM speed in the
HDD-06V75E to HDD-6V20E models

10kHz PWM speed in the
HDD-9V30E

Ambient operating
temperature range

-40 to
+85°C. Amperage derating curve decreases from full amperage at 40°C to
zero amperage at 100°C when a proper heat sink and air flow pattern are in
use. Design your application so that you do not exceed 80% of the max amperage
at a given temperature in order to anticipate load variations.

These diodes are available in the
price list shown above. Normally, the diode is installed across the load. If
the wiring is long, the diode should be installed so that it supresses the
inductive load AND the inductive long wires. Some high speed loads or h-bridges
might use a MOV instead of the diode.
